History explorer

Pick a game and a period inside one rules era, then look at how often each number was drawn, how many draws since each number was last seen, and which pairs appeared together most. Every figure is computed from the official archive on this site.

Linked views: pick a number or a draw

Totals in the chart and table above use every draw in the selected range; the grid shows 25 draws at a time, newest first.

Filter lab: which past draws had these properties?

Build a filter from small, readable rules. It runs on the same game, era and range as the chart. A filter describes history; it does not change any future draw.

Saved investigations and share links contain only the game, era, dates, rules and the data revision. Never put ticket numbers, names, contributions or notes in them. Discussion drafts are copied to your clipboard for you to review and post yourself in the Community.

Reality check: would a history-based pick have done better than random?

A bounded walk-forward test inside the selected era. For each test draw, tickets are built only from draws before it, then scored. A seeded random strategy with the same ticket count is always shown beside it. This measures the past; it predicts nothing.

Data quality, sources and coverage for this game

Question

History, not prediction. Every eligible number is equally likely in every draw. Frequencies and gaps describe the past only; "hot", "cold" or "overdue" numbers have no better chance next time. Older rule eras had different eligible numbers, so comparisons are kept within one era.
